Typical Duration
Quick Answer
Pink eye (conjunctivitis) typically lasts 7–14 days for viral cases and 5–10 days for bacterial cases. Bacterial pink eye clears faster with antibiotic eye drops, often improving within 24–48 hours of starting treatment. Allergic conjunctivitis persists as long as the allergen exposure continues.
Duration by Type
| Type | Duration | Contagious? | Treatment |
|---|---|---|---|
| Viral | 7–14 days | Yes, up to 14 days | Supportive care (cold compresses, artificial tears) |
| Bacterial | 5–10 days (2–3 with antibiotics) | Yes, until 24 hrs on antibiotics | Antibiotic eye drops or ointment |
| Allergic | As long as allergen present | No | Antihistamine drops, avoiding triggers |
| Chemical/irritant | 1–2 days | No | Flushing with water, lubricating drops |
Day-by-Day Timeline (Viral)
| Day | What to Expect |
|---|---|
| 1–2 | Redness, watery discharge, gritty feeling begins |
| 3–5 | Symptoms peak; eye may be crusted shut in the morning |
| 5–7 | May spread to the second eye |
| 7–10 | Symptoms begin fading |
| 10–14 | Full resolution for most cases |
Factors That Affect Duration
- Cause: Viral cases last longer than bacterial. Allergic pink eye won't resolve until allergen exposure stops.
- Treatment timing: Starting antibiotic drops early for bacterial pink eye shortens the illness significantly.
- Immune health: People with weakened immune systems may experience longer or more severe episodes.
- Hygiene: Touching the affected eye and then the other eye can spread the infection and prolong symptoms.
How to Speed Up Recovery
- Apply cold compresses to reduce swelling and discomfort.
- Use preservative-free artificial tears to flush irritants.
- Wash hands frequently and avoid touching your eyes.
- Replace contact lenses and cases; switch to glasses until symptoms resolve.
- Wash pillowcases and towels daily.
When to See a Doctor
- Severe pain or sensitivity to light
- Blurred vision that doesn’t clear with blinking
- Symptoms that worsen after 3–4 days
- Green or yellow discharge (suggests bacterial infection needing antibiotics)
- Newborn with any eye discharge (seek immediate care)
Pro Tips
Discard used contact lenses and cases and switch to glasses until symptoms fully resolve to avoid reinfection.
